Genetic identification and purity testing based on DNA analysis represents an important part of modern quality assurance, as well as in the testing for adulteration in agricultural production and food industry. We are working with a number of our clients on Intellectual Property (IP) issues including Plant Breeders Rights. Our DNA profiling platforms can be also used for paternity testing in animals, both in agriculture and ecological/population research.
DArT P/L has capacity to perform genetic identification of any organism, especially when using our DArTseq platform.
We can validate the identity of a particular seed sample of any crop given a set of reference profiles for varieties has been generated. By working with Grains Research and Development Corporation (GRDC), we have developed a comprehensive set of references for wheat and barley varieties grown in Australia. We can provide a routine service, not only for varietal identification but also for precise estimation of the level and type of contamination in the sample.
If the reference set is not available we can certainly test any sample against a reference sample(s) provided by the client. As both the DArT and DArTseq platforms use hundreds to tens of thousands of markers, our genetic ID work offers significantly more power and reliability compared to other platforms, which are often based on a limited number of monoplex assays.
Intellectual Property issues are important for a number of our clients. Some use our service to obtain a comprehensive, and completely unique DNA fingerprint of their new variety. In some cases, we were able to identify a unique fingerprint based on epigenetic variation, which was diagnostic for a difficult to test quality attribute, like taste. Other clients contract us to detect adulteration of their product with inferior material.
Not only can we detect such adulteration, but we can also quantify and possibly identify the contaminant. Our immense database of whole genome profiles, containing well over 100 different organisms, offers us an opportunity to compare any sample submitted to us to prior processed material.
Our genome profiling service for animals is increasingly popular, which includes paternity testing. This is particularly important for most population genetics and landscape genomics projects. Not only is our offering of a low price is an attractive component of such a service, the depth of profiles produced offers additional insight into the materials provided, which is not available when using lower plex platforms.
